Question
As we move down the group in alkaline earth metal, what happens to the ability to form peroxides?
- Remains same
- Increases
- Decreases
- Group 2 doesn't have the ability to form peroxide.
Hint:
Down the group peroxide forming ability increases.
The correct answer is: Increases
- As we move down the group in alkaline earth metal, what happens to the ability to form peroxides increases.
- The covalent bond between the two oxygen atom is relatively weak.
- The electrons in the peroxide ion will be strongly attracted by bigger +2 ions.
